Hot melt adhesive emulsion process

ABSTRACT

a novel process for applying an adhesive to a substrate is disclosed, which process comprises: 
     A. melt blending a monoalkenyl arene/conjugated diene block copolymer, tackifying resin and extending oil to form a hot melt adhesive composition, 
     B. emulsifying the hot melt with water and an emulsifying agent, and 
     C. applying the resulting emulsion as a film on a substrate. 
     Preferably, the block copolymer is a styrene/isoprene block copolymer and the tackifying resin is selected from the group consisting of diene-olefin copolymers, hydrogenated resins, esters of resin, polyterpenes, terpenephenol resins, and polymerized mixed olefins.
